How we approach conservation rooflights in Biggleswade
Thinking about conservation rooflights in Biggleswade? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Biggleswade, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
Jobs in Biggleswade are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Do you need permission in Biggleswade?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
